Managing 2,4-D and Dicamba in Enlist™ and Xtend® Soybean

Shawn P. Conley, Soybean and Wheat Extension Specialist

Enlist™ and Xtend® traits are engineered to provide resistance to the group 4 synthetic auxin herbicides 2,4-D and dicamba, respectively. These traits allow, for the first time, POST applications for control of broadleaf weeds in soybean and cotton. However, many broadleaf plants are inherently sensitive to 2,4-D and dicamba, and the use of the Enlist and Xtend technologies requires proactive stewardship of the herbicides.
